Privacy and data processing
How public links, caption files and support messages are processed by BES123.

Current audio fallback
If the public caption track cannot be read, BES123 attempts to obtain the public video audio through TikWM and recognizes speech locally in your browser with Whisper. First use downloads a speech model; keep the page open. Maximum 5 minutes and 12 MB. The resolver can be rate limited or unavailable. Speech recognition may make mistakes or generate text during music or silence; review results. There is no translation or OCR.
Public video links
Submitting a link sends that URL to the site’s Cloudflare-hosted function. The function requests the public TikTok page and, when available, a linked caption file. This necessarily makes requests to TikTok and its content delivery providers. If captions cannot be read, the public video link is sent to TikWM to resolve an audio URL. The browser retrieves public video media directly from the resolved TikTok CDN URL and decodes its original audio track locally (up to 12 MB and 5 minutes). If server-side resolution is rate limited, the browser sends the public link directly to TikWM. Your browser downloads a Whisper speech model from Hugging Face and runtime files from jsDelivr, then performs speech recognition locally. Those providers process network requests under their own policies. No transcript is written to an application database.
Local subtitle files
Files selected through the subtitle-file input are read and parsed in your browser. That file content is not uploaded by this feature. Copy and download actions are also handled in the browser. Content remains visible in the current page until you clear it, reload or close the page.
Hosting and third parties
Cloudflare processes network requests to host and protect the website. Hosting and security systems can process technical data such as IP addresses, request URLs and security events under their own settings and policies. This is separate from an application transcript database. The site loads fonts from Google Fonts, which causes your browser to contact that service.
Support messages
If you email [email protected], the support mailbox receives the content and details you choose to send. Avoid private videos, passwords, access tokens or sensitive transcripts. To ask about a support message or request its deletion, contact the same address.
Use only necessary information
Do not submit private links or material you do not have permission to process. This notice describes the current tool workflow. Material changes to that workflow will be reflected here.
